I have reviewed and understood how is possible to achieve highly realistic for Meshes.
Firstly. Mehs Edges (creases) painted gradient (used object color) And those corners, with more acute angles painted more clearly. Those edges that are painted with a large angle is less noticeable. With this admission form looks more realistic.
Second.I also analyzed the light and shadow. I drew attention to the areas that are a little deeper than the main surface (dents) have a slightly graying (without shine and reflections).
in this image you can see how great works gradient for Mesh Edges
In this image I want to show how you can get stuff like blue patina. Note the second image. There clearly show that these effects are directly dependent on the colors of the edges (gradient)
I’ve been doing different settings to display the mesh in Rhino.
Great that there is an opportunity to show the edges.
It is a pity that their settings are limited.
Great that there are preferences for the shadows. But sorry that can not configure the shade saturation and color for just dented surfaces.
May I hope that you are interested in my proposal?
And will add these innovations in next release Rhino 5?
